RATIONALE: Drugs used in chemotherapy, such as carboplatin, cyclophosphamide, etoposide, and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Isotretinoin may help neuroblastoma cells become more like normal cells, and grow and spread more slowly. Giving combination chemotherapy before surgery may make the tumor smaller and make it more likely that the tumor can be surgically removed. It is not yet known what is the minimal amount of chemotherapy needed to achieve sufficient tumor shrinkage to control intermediate risk neuroblastoma and prevent tumor recurrence or metastases.
PURPOSE: This phase III trial is designed to reduce therapy for patients with favorable biology intermediate risk neuroblastoma by decreasing the number of chemotherapy cycles administered and by allowing for up to 50% residual tumor volume for patients with localized disease.

- Definitive Determination of the Prognostic Ability of 1p and 11q [ Time Frame: At baseline ]Addressed by a descriptive comparison of the EFS and OS rates for patients with 1p loss vs without 1p loss, and for those with unbalanced 11q vs normal 11q.
- Comparison Between Reduce Intensity of Therapy for Patients With Stage 4 Neuroblastoma and Favorable Biological Features and Patients < 1 Year of Age With Stage 4 Neuroblastoma Treated on COG-A3961 [ Time Frame: Up to 3 years ]Addressed by the interim stopping rule and the comparison, by INSS stage, to the historical EFS rate of the analogous cohort of patients < 1 yrs of age.
- Comparison Between Reduce Intensity of Therapy for Patients With Unfavorable Histology Neuroblastoma and Patients Unfavorable Histology Neuroblastoma Treated on COG-A3961 [ Time Frame: Up to 3 years ]Addressed by the interim stopping rule and the comparison, by INSS stage, to the historical EFS rate of the analogous cohort of patients < 1 yrs of age
- Reduced Surgical Morbidity for Patients With Stage 4S Neuroblastoma [ Time Frame: Up to 3 years ]Descriptive analyses of the proportion of stage 4S infants that experience a surgical or post-operative event.
- Outcome of Patients With Stage 4S Neuroblastoma Who Are Unable to Undergo Biopsy for Biology-based Risk Assignment [ Time Frame: From baseline to up to 10 years ]Kaplan-Meier curves and lifetables of Event Free Survival (EFS) and Overall Survival (OS) rates will be generated to describe the outcome of the stage 4S infants unable to undergo biopsy.
- Correlation Between Extent of Surgical Resection With the Maintenance of Local Control, Event Free Survival (EFS) [ Time Frame: Up to 10 years ]To test the predictive ability of the extent of surgical resection for EFS, log-rank tests will be performed comparing complete surgical resection vs. without complete surgical resection.
- Correlation Between Extent of Surgical Resection With the Maintenance of Local Control, Overall Survival (OS) Rates [ Time Frame: Up to 10 years ]To test the predictive ability of the extent of surgical resection for OS, log-rank tests will be performed comparing complete surgical resection vs. without complete surgical resection.
- Correlation Between Extent of Surgical Resection With the Maintenance of Local Control, Surgical Complication Rate [ Time Frame: Up to 10 years ]To test for the association of the extent of surgical resection (CR vs <CR) with surgical complications rate (complications of any kind vs no complications at all), a chi-square test will be performed.
- Second-event-free Survival (E2FS) [ Time Frame: From the time of the first progressive, non-metastatic event until the subsequent occurrence of relapse, progressive disease, secondary malignancy, or death; up to 3 years ]E2FS (from time of first event) will be calculated to describe the outcome for patients who have a first progressive, non-metastatic event during Observation and then receive protocol retrieval therapy.

8 courses of initial chemo - carboplatin, cyclophosphamide, doxorubicin hydrochloride, etoposide, filgrastim.
-
Patients < 12 months of age with stg 3, 4, or 4S disease who achieve a very good PR (VGPR) to chemo (with the exception of resolution of skin or liver metastases in stage 4S patients) proceed to observation. Patients 12-18 months of age with stg 3 or 4 who achieve VGPR proceed to isotretinoin therapy. No VGPR proceed to retrieval chemo - cyclophosphamide and topotecan hydrochloride. Some patients may also undergo surgery.
-
Must already be enrolled on protocol COG-ANBL00B1
-
Simultaneous enrollment on COG-ANBL00B1 and this study allowed for clinical situations in which emergent treatment may be indicated including, but not limited to, the following criteria:
- Epidural or intraspinal tumors with existing or impending neurologic impairment
- Periorbital or calvarial-based lesions with existing or impending cranial nerve impairment
- Anatomic or mechanical compromise of critical organ function by tumor (e.g., abdominal compartment syndrome, urinary obstruction)
- Asymptomatic but, in the opinion of the treating physician, it is in the patient's best interest to begin chemotherapy immediately due to impending risk of neurologic impairment or organ dysfunction
-
-
If patient receives study chemotherapy prior to undergoing diagnostic biopsy, the biopsy must be performed within 96 hours of beginning study therapy
-
The only exception to this requirement is for patients with stage 4S disease who are considered too ill to undergo a diagnostic procedure will be waived the requirement for diagnostic tissue submission but will still need to be enrolled on COG-ANBL00B1
- For patients with stage 4S disease who are very ill and in whom an open biopsy to obtain tissue for diagnosis and biologic studies is considered medically contraindicated, every effort should be made to obtain some tumor tissue by either fine-needle aspiration of a metastatic site of disease and/or sampling of involved bone marrow, so that this tumor sample can be submitted for MYCN determination
-
-
Patients who require emergent therapy, either prior to the diagnostic biopsy or before biology features are available, can be enrolled simultaneously on COG-ANBL00B1 and COG-ANBL0531 to receive emergent protocol therapy
- In emergent circumstances, COG-ANBL0531 protocol therapy may be initiated prior to enrollment on study as long as the patient has neuroblastoma by clinical diagnosis, all other COG-ANBL0531 eligibility criteria are met, and the COG-ANBL0531 Initial Therapy consent has been signed prior to starting protocol therapy; in this circumstance ANBL0531 enrollment must occur within 4 working days of starting protocol therapy
-
Clinical situations in which emergent enrollment and treatment may be indicated include, but are not limited to, the following circumstances:
- Epidural or intraspinal tumors with existing or impending neurologic impairment
- Periorbital or calvarial-based lesions with existing or impending cranial nerve impairment
- Anatomic or mechanical compromise of critical organ function by tumor (e.g., abdominal compartment syndrome, urinary obstruction)
- Evolving hepatomegaly in infants less than 2 months of age
PATIENT CHARACTERISTICS:
- See Disease Characteristics
PRIOR CONCURRENT THERAPY:
